Dear all,
We output some data from SSI I/F of i.MX6Quad.
OS is Android4.4.3 of NXP BSP.
However, one core is occupied because the data are handled by BusyLoop,
Therefore we want to use SDMA.
Would you tell me the method using SDMA in SSI data transfer?
If there is a sample cord, would you send it?
Best Regards,
Yuuki
Hi Yuuki
SDMA with SSI is supported in Linux, refer to attached Linux
Manual Table 4-1. SDMA Channel Usage, Table 28-1. Stereo Codec SoC Driver Files
file fsl/fsl_ssi.c - SSI CPU DAI driver for stereo CODEC ALSA SoC
Board Support Packages (32)
L3.14.52_1.1.0_MX6QDLSOLO (REV L3.14.52_1.1.0)
Best regards
